Mobile Core i7 920XM, Clarksfield: Nehalem on-the-go

Clarksfield Summary
The following three slides summarize what you get with Clarksfield: basically a mobile version of Lynnfield and P55.
The bottom line is that Clarksfield is all about performance. Nehalem can be very stingy when it comes to power use, but as we will see later maximum power draw can still be very high. If you're looking for a new laptop that will get Intel Atom levels of battery life, Clarksfield definitely isn't going to fit the bill. What it should offer is better performance within the same power envelope as previous processors, so instead of a QX9300 you can get an i7-920XM.
One final slide from Intel that I had to pull out shows that marketing as usual is getting a little carried away. I suppose the real question is what qualifies as a "gaming laptop", but as someone who regularly reviews high-end laptops I'm relatively certain they're not getting any closer to displacing gaming desktops for the vast majority of users. When you can purchase a $1000 desktop that offers 2-3x the performance of even the fastest $3000+ "gaming laptops", that's a tough pill to swallow. Needless to say, just because a laptop has "DirectX 10 capable" graphics doesn't mean it's a "gaming laptop". I would argue that anything less than the GeForce 8800M/9800M/GTX 260M hardly qualifies as a gaming solution, but then some people are more than happy to make do with AMD's HD 3200.
Okay, enough talk… let's see some actual performance numbers.

I consider any dedicated card with at least 16SP's and at least 512MB of dedicated memory to be a gaming laptop; 16 SP's IS the ABSOLUTE minumum, but that should be enough to run everything ecxept maybe crysis (Which I really hate anyway) at 720p or higher with playable frame rates. Who cares about eye candy? As long as the game runs smoothly. Desktops are for eye candy, laptops and consoles are just for gaming.maomao0000 - Sunday, October 11, 2009 - link

Man, as someone who hasn't used a desktop as personal computer for the last 4 years, the move to laptop was a very difficult one. You have the convenience but lack the performance. Now couple this processor with two raid ssd's and 8 gigs of ram in a 64bit Windows 7 laptop and you finally have a beast of a machine in your probably burning lap.I'd love to get that setup and finally not feel as though I'm loosing out to a desktop in anyway. The only true limitation is Crysis, but seriously that game sucked anyway!
Can't wait!

Heh, "Gamers Are Going Mobile". My video card is the size of some laptops. And I'm not playin on no 15" screen.FXi - Thursday, September 24, 2009 - link
I have to say the mobility right now is more of a draw than a higher level of eye candy. Now mind you, I have both laptop and desktop so if I really crave eye candy, I can go to the desktop room and game.But with two little ones, I find that my 'gaming time' is often measured in 20 min spans here and there, and that being able to surf or get some work done wherever the kids happen to be is a benefit that I very much enjoy. So I can run Witcher on my old 7950M, windowed @ 1620 and have the settings lower and be "ok" with that.
Mind you I do crave a bit more oomph, a more modern machine, but I can bide my time. The mobility is very nice, and I don't LAN (no time!). Having SLI or a higher end mobile chip simply means the laptop is "acceptable" for a longer period of it's life.
I won't argue the bang for the buck. Mobile gaming is pricey and not cost effective. But the mobility is nice, the space taken up by a machine I can throw in the closet is also nice. And within some limits, lower res or lower eye candy is acceptable as payment for that mobility.
Now I just need USB 3 (USB changes only happen every 10 years or so) and then I might consider upgrading.

When checking my laptop for Ubuntu vs Xp battery life, I accidentally ran my first XP test with my standard undervolt on, didn't seem to impact battery life any.ambientmf - Thursday, September 24, 2009 - link
Am i the only one who thinks these chips are ridiculously overpriced? I would never drop more than $350 on a CPU even in a desktop, it just doesn't seem economical for a $1K laptop processor. especially if it's only running at a 2.0GHz base.The cheaper options seem really underwhelming and like others have said, the thermal output of these chips just doesn't make sense for a laptop.

The big problem with gaming laptop's is that they aren't balanced. The display is always at higher res than the cpu/gpu can drive.I'd get a gaming laptop if it can drive all current gen games at max settings at the native res of the panel it comes with. Even if that res is <1080p.
If it can't do that, then I've spent a lot of money on something that's already behind the desktop I can get for cheaper.

... if there is one? I mean that that 1.6 Ghz part looks very nice: quad-core with HT and turbo.I think someone could make a decent notebook, not a desktop replacement out of a 720QM.

Shouldn't the Quad core mobiles be 32nm and the Dual cores 45nm? I know that's not the case but what was Intel thinking? It doesn't even look like there's a refresh of the Quad's to 32nm in the Spring.Crazy, cuz they look like good chips with a shrink.
